A Queensland dairy company has sparked a heated online debate after announcing on its Facebook page that it will not seek Halal certification for its products.

The posting by Maleny Dairies has triggered more than 24,000 Likes, with some praising the business and others accusing it of promoting xenophobia.

"We do not wish to increase the costs of our products to cover the expense of Halal certification. We prefer to make sure our local farmers receive a fair and sustainable price for their milk," the post states.
